Dude could't be more stupid; even if you actually like the girl, and you're not just going out with her out of fear, you should know how scary a power like that can be. You answer a creepy question like that in that way, 9/10 she's going on a killing rampage. Even worse, when he finds out (go to beginning of chapter 1) he's gonna freak out and she's gonna lose it, like "hey, you said it was fine!" and probably entering full yandere mode. I really hope it doesn't end up being that predictable, but i'm not that hopeful.
